Here's my story
07 wrangler stock with 265 dura-trax
Installed a 2" lift and swapped the dura-trax for 50% wranglers for the summer and keep the dura-tax for winter and no time for wheel alignment.
had to drive max 80k/hr and slow down for bigger bumps.
Got wheel alignment done
DEATH WOBBLE got worse actually
Removed tires and reinstaled dura-trax
So I have read about those who are hitting their heads on a brick wall trying to solve their DW problem and have spent money and time doing so.
My advise is find someone who doesn't have the problem and convince them to swap tires with you for a test drive. You never know and this doesn't cost anything to test out. Good luck!
